"I '2X HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 737,976, datedSeptemberl, 1903.

Application ined Maat 16,1903. serrano. 147,961'. (remodel.)

To all whom it may concern:

Be it known that I, SILAS TUTTLE, a citizen of the United States, and aresident of the city of New York, (borough of Brooklyn,) in the countyof Kings and State of New York, have invented a new and ImprovedIfIot-Air Register, of which the following is a full, clear, and exactdescription.

rlhis invention relates to improvements in registers designed to beplaced in the side walls of a room for the diffusion of hot air, and anobject is to secure an enlarged opening from the lower room to the upperby projecting the register some distance into the room, thus allowing aportion of the iioor to be cut out for a larger pipe than can be passedup through the ordinary partition.

Another object is to control the air delivered by directing it wholly,partly, or not at all into either the lower or upper room, as may bedesired. A

Another ,object is to provide a simple and convenient means foroperating and holding the damper as adjusted to produce the aboveresult.

Another object is to provide a simple and effective method of fasteningthe register to the wall without exterior screws or nails and whichshall also form a connection adjustable to the varying thicknesses oflath and plaster between the line and the face of the wall against whichthe register is placed, as hereinafter described.

Another object is to so construct the damper that it will not bedistorted by heat and be generally oli' increased strength to resistabuse.

I will describe a register embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate correspondingparts inall the figures.

Figure l is a perspective View of a register embodying my invention.Fig. 2 is a section thereof on the line 2 2 of Fig. 3. Fig. 3 is asection on the line 3 3 of Fig. 2 with a part broken away, and Fig. 4 isa sectional view of the damper,

Referring to the drawings, 5 designates the frame of the register, whichis made deeper at the bottom than at the top, allowing a tin flue to beplaced having double the capacity in its lower portion than at its upperportion 5 5 in the register. The register-frame is placed against theface of the wall at the floor after removing a portion of thebase-board. The tin box 9, formed to receive the register, is broughtthrough the opening of the frame, 6c the edges are trimmed to suit thethickness of the wall, and the edges are then turned over the frame. Theface-plate and the damper are then replaced and screwed iirmly againstthe tin, thus holding the register securely in position.

In the front of the frame is removably placed the grille face 6. Thisgrille face 6 is held in place by means or screws 7. The damper 8 isdesigned to swing relatively to the face 7o G, so as to eiectually eutoff the passage of hot air through said face or to direct it through theface, wholly or partiallycutting ofi? the register box or ilue 9,' towhich the frame 5 is attached. It may be here stated that this damper Sis concaved both transversely and lengthwise. By this means it ispractically impossible to distort the damper by heat or abuse, as oftenhappens with flat dampers. At its upper portion the damper has trun- 8onions l0 for,engaging in bearing-sockets l1, formed on the inner sideor' the frame, and it will be noted that the face 6 forms a frontbearing for the trunnions and holds the saine in place. At its sides,near the top, the 8 5 face G is provided with inwardly-extended brackets12, on which the trunnions may rest when placing the same in thesocket-bearings, as will be hereinafter described. At one end, near thetop, the face 6 is provided with a slot 9o 13, in which a lever la ispivoted. The inner portion of this lever is provided with a slotl5,which is eccentric to the pivot of the lever, and in this slot a pin i6extends from the damper.

In theoperation of this part of the invention by pressing downward onthe outer end of the lever 14E the damper 8 may be swung to and held inany desired open position. Of course by moving the outer end ot' the leroo ver in the opposite direction thedaniper will be swung to and heldin closing position.

In assembling the parts the trunnions l() of the damper are to besupported on the brackets 12 and the damper held closely against theface (3 With the pin 1G in the slot 15. NOW the trunnions may be readilyinserted in the socket-bearings l1 and the front plate placed inposition and secured by means of the screws '7.

Having thus described my invention, I claim as new and desire to secureby Letters Patentv I. In a register, a frame having socket membersforming bearings opening outward, a damper, trunnions on said damper forengaging in said socket members, a front plate secured to the frame andforming outer bear- -ings for the trunnions, and brackets on the innerside of the front plate for supporting the damper when assembling theparts.

2. In a register, afralne having,` socket menibers forming` bearings,the said socket niembers opening' outward or to the front, a damper,trunnions on said damper t0 engage in said s0cket-bearings, a grillefront removably secured to the frame and forming the outer bearings forthe trunnions, and brackets on the inner side of said grille front forsupporting the trunnions when assembling the parts.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
